To check a used phone in Poland, inspect it in person before any money changes hands: confirm the model and storage in settings, test the screen, battery, cameras, speakers and charging port, check that the phone is not locked to an account, and ask for the original proof of purchase. Meet in daylight, pay only after the checks pass, and keep a written record of the deal.
The used phone market in Poland runs on classifieds, and most deals happen face to face in a cafe, a shopping centre or outside a metro station. That is convenient, but it puts the whole inspection on you. Nobody will do it for you at the meeting, and once you have handed over cash, getting it back is a conversation, not a procedure.
This guide is a working checklist for a private buyer. Read it on the tram on the way to the meeting, or keep it open on your own phone while you hold the seller's. It covers what to ask before you go, what to bring, what to press and tap at the viewing, which defects hide well, and how to close the deal without leaving yourself exposed.
- Ask for the exact model, storage size and IMEI before the meeting, and confirm the phone is not tied to a previous owner's account.
- Bring your own charger, cable and a SIM or eSIM you can test with, plus a second phone to photograph the IMEI and the listing.
- Test screen, battery, cameras, speakers, microphones, charging port and every button, not just the home screen.
- Pay only after the checks pass, get a written receipt with the IMEI, and keep the conversation inside the platform until the deal is done.
What should you ask the seller before the meeting?
Ask for four things in writing before you agree to meet: the exact model name and storage size, the IMEI, the age and purchase date, and whether the phone has been repaired. A seller who answers these quickly and precisely is easier to deal with than one who sends a single photo and a price.
Model and storage matter because the same phone name can cover 64 GB, 128 GB and 256 GB versions with very different values. Ask for a screenshot of the settings screen showing model, storage and battery health where the system reports it. That screenshot also tells you the phone is switched on and working at the time of the message.
Documents and proof worth requesting
Ask whether the original receipt or invoice still exists, and whether the phone was bought in Poland or brought in from abroad. A receipt with a date and a shop name is the simplest proof of age. If there is no receipt, ask where it was bought and whether a warranty card or an email confirmation exists.
None of this proves ownership on its own. Treat documents as one signal among several, and check the official sources if you want to know what Polish consumer rules say about a given situation. The Office of Competition and Consumer Protection publishes guidance for buyers at UOKiK, and public service information sits at gov.pl. Read those pages yourself rather than relying on a seller's summary.
Also ask why the phone is being sold, and whether it has ever been serviced or had the screen or battery replaced. A replaced battery is not automatically bad news. An unmentioned replacement discovered at the meeting is a reason to slow down.
What to bring to the viewing
Bring a charger and cable that you know work, a SIM card or an eSIM you can activate, and a second phone for photos. Add a small cloth and a torch if you have one on your keyring. The goal is to test the phone with your own equipment, not the seller's.
Before you leave home, save the listing and take a screenshot of the photos and the price. On EX & GO you can find the seller's listing and message thread in one place, and the current posting rules are published at /en/rules if you want to know what the platform expects from a listing. Moderation of a listing is not a check of the phone's condition or of who the seller is, so the inspection stays with you.
Choose the meeting place with care. A busy cafe, a shopping centre or a carrier's showroom gives you light, seating and people nearby. Avoid meeting in a flat or a stairwell, and avoid paying in a place where you cannot sit down and test properly.
Step by step: the inspection checklist at the meeting
Work through these steps in order and do not skip ahead because the phone looks clean. Each step takes under a minute, and the whole sequence fits into about fifteen minutes if the seller is patient.
- Confirm the model and storage in Settings, then compare them with the listing and with the box if one is present.
- Open the dialler and type the IMEI code to display the phone's IMEI, then compare it with the number the seller sent and with any label on the box.
- Check that no account is signed in that you cannot remove, and ask the seller to sign out of their account in front of you before you pay.
- Test the touchscreen across all four corners and the middle, dragging an icon slowly to catch dead zones.
- Look at a white image and a black image at full brightness for stains, shadows and burn-in, then tilt the phone under light to spot scratches.
- Open the battery screen and read the reported health or cycle count if the system shows it, then ask how long the phone lasts on a normal day.
- Take a photo with each camera, front and back, and record a short video with sound to test the microphone.
- Play audio at full volume, then cover the speaker and check the earpiece during a real test call.
- Plug in your own charger and confirm the phone charges, then test the port by wiggling the cable gently for a loose connection.
- Test Wi-Fi, mobile data with your SIM, Bluetooth with your own headphones, and the fingerprint or face unlock.
- Press every physical button, check the silent switch if there is one, and test vibration.
- Restart the phone once and confirm it boots normally without a password you do not know.
If the seller rushes you past any step, treat that as information about the deal, not about the phone. A genuine seller with nothing to hide will let you run a fifteen minute check, because they want the sale to close as much as you do.
What hidden defects should you watch for?
The defects that cost the most are the ones that do not show on a home screen: a tired battery, a screen replaced with a cheap panel, water damage, a camera with a scratched lens, and a phone still tied to someone else's account. Most of them surface within a few minutes of deliberate testing.
A cheap replacement screen often shows uneven brightness at the edges, weaker colours at an angle, or a touch layer that misses fast taps. Water damage can leave a faint tide mark under the glass or corrosion around the charging port. A battery that drops several percent while you stand there is telling you something the settings screen will not.
Account locks are the most expensive surprise. If the phone still asks for a previous owner's password after a restart, stop. The same applies to a phone reported as lost or stolen, which is why the IMEI matters: keep the number and check it against the official sources you trust before paying.
| What to check | How to check it | What a problem looks like |
|---|---|---|
| Model and storage | Settings, then the box label | Numbers do not match the listing |
| IMEI | Dialler code, box label, seller's message | Three numbers that disagree |
| Account lock | Restart and watch the first screen | A password prompt you cannot pass |
| Screen | White and black images, slow drag test | Dead zones, stains, uneven edges |
| Battery | Battery screen plus a live drain check | Fast drop, swelling, heat |
| Cameras | Photo and video with each lens | Blur, spots, a scratched lens |
| Charging port | Your own cable, gentle wiggle | Charges only at an angle |
| Water damage | Torch on the port and edges | Tide marks, corrosion, fog in a lens |
How do you close the deal safely?
Close the deal only after the checks pass, and keep a record of what you agreed. Write a short receipt by hand or in a message: date, place, model, storage, IMEI, price and both names. Photograph it. That single page is worth more than any verbal promise made at the table.
Pay in a way you can trace. Cash is common at these meetings, but a bank transfer leaves a record that a handover of notes does not. If you pay cash, count it in front of the seller and note the amount on the receipt.
Before you leave, ask the seller to remove their account, their SIM and any memory card, and confirm the phone has been reset. Then check that the phone starts fresh and asks you to set it up. If the seller wants to keep the messages open, that is fine, but the reset should happen while you are still there.
On EX & GO, direct deals are arranged between the parties, and optional Safe Deal may be available on eligible listings under its own payment terms. Read those terms before you rely on them. If something goes wrong after the meeting, the support pages at /en/support explain where to raise the issue. Compare a few similar listings on the platform before you agree a price, so you know what the model sells for in your city.
Where money queries matter, it helps to see the wider market rather than one listing. Browse comparable phones in your category on EX & GO before the meeting, used phones, and check current asking prices in your area rather than trusting a single seller's figure. If you are still deciding between models, used phones in Warsaw, and compare what each one costs used before you commit to a viewing.
Frequently asked questions
How do I check a used phone in Poland without meeting the seller?
You can do the paperwork remotely but not the physical inspection. Ask for photos of the settings screen, the IMEI and the proof of purchase, and confirm the model and storage in writing. A remote check cannot confirm the screen, battery or charging port, so treat any phone you have not held as unverified. If a seller refuses a meeting and pushes for a deposit by transfer, that is a reason to walk away.
What should I check first when I hold the phone?
Start with the model, storage and IMEI, because those three numbers decide whether the phone is the one advertised. Then restart it and watch for an account lock. Only after those pass should you spend time on the screen, cameras and battery. If the basics fail, the rest of the inspection does not matter, and you can end the meeting politely and quickly.
How can I tell if the battery has been replaced?
Ask directly, and compare the battery health figure with the age of the phone. A three year old phone reporting full health is worth a second look. Uneven gaps around the frame, a slightly raised back panel or a screen that sits proud of the body can point to a repair. None of this is proof on its own, so weigh it with the seller's answers and the receipt.
Is a receipt enough to prove the seller owns the phone?
No. A receipt shows a purchase happened, not who owns the phone today. Use it together with the IMEI, the seller's willingness to sign out of their account in front of you, and a written record of the deal. If you need to know what Polish rules say about a specific situation, read the official guidance at UOKiK or gov.pl rather than relying on a seller's explanation.
Should I pay a deposit before the meeting?
Be cautious with deposits. A deposit sent before you have seen the phone gives you nothing to hold if the seller stops answering. If you do agree to one, keep it small, send it by a traceable method, and put the amount and the reason in the message thread. Many buyers simply refuse deposits and meet in person instead, which removes the problem.
What if the phone fails a check at the meeting?
Say so plainly and do not pay. You are under no obligation to complete a deal because you travelled to the meeting. Note what failed, keep the messages, and report the listing through the platform if the phone clearly differs from the description. Then look at other listings in your city and compare prices again before your next viewing.
Your next step
Pick one listing, send the four questions in a single message, and book a meeting in daylight with your charger and a second phone in your bag. Run the twelve steps in order. If everything passes, write the receipt, reset the phone together, and pay by a method you can trace. If anything fails, leave it and move to the next listing.
